| Model to verify the value of ? ( Pie.) | Seema RK | 28 Jan 2009 |
We know that Pie is an irrational number its value is approximately 3.14, 22/7 or 355/113. The great Indian mathematician Arabhatta was using ? = v10. But for the student of secondary level it is not quite easy to accept its value without any logic. In this article we are giving one method to verify that the value of ? is approximately 22/7 or 3.14.

| THUNDER AND LIGHTINING | sobha wilson | 24 May 2008 |
The nature’s most spectacular display of static electricity is a flash of lightning. People of ancient civilizations believed that thunder and lightning indicated the anger of their gods. During a thunderstorm, raindrops and hailstones hurl up and down inside a thunderstorm producing charges of static electricity. Positive charges move to the top of the cloud, negative charges to the bottom. The earth is positively charged, so the negative charges in the clouds are attracted downwards. This is why lightning

| ONLINE EDUCATION SYSTEM | SRIMATHI | 25 Apr 2008 |
The main objective is to classify the students in order to predict their final grade Based on features extracted from logged data in an educational web based system. We can give the grades to students through data mining. In data mining we have multiple classifiers. A combination of multiple classifiers leads to a significant improvement in classification performance. We use genetic algorithm to optimize the prediction accuracy.

| Fingerprints | SRIMATHI | 25 Apr 2008 |
Fingerprints offer an infallible means of personal identification. That is the essential explanation for their having supplanted other methods of establishing the identities of criminals reluctant to admit previous arrests
Many areas of scientific study involve the collection of large amounts of data. Such data must be organized in order to be useful
The patterns of ridges on our finger pads are unique: no two individuals—even identical twins—have fingerprints that are exactly alike
